下图是一种染料敏化太阳能电池的示意图。

电池的一个电极由有机光敏染料(s)涂覆在TiO₂纳米晶体表面制成，另一电极南导电玻璃镀铂构成，电池中发生的反应为：

TiO₂/STiO₂/S*（激发态）

TiO₂/S*→TiO₂/S⁺+e^-

I₃^-+2e^-→3I^-

TiO₂/S⁺+3I^-→2TiO₂/S+I₃^-

下列关于该电池叙述错误的是 [ ]

A．电池工作时，I^-离子在镀铂导电玻璃电极上放电

B．电池工作时，是将太阳能转化为电能

C．电池的电解质溶液中I^-和I₃^-的浓度不会减少

D．电池中镀铂导电玻璃为正极

文段阅读训练。

　　读书需要选择。如果不善选择，一生什么事不干，光读别人的书也读不完，那又有什么意义呢？读，失去了意义；书，也失去了存在的价值。

　　我的办法是，翻遍所有能接触到的书，因为不亲自翻一翻就不知好坏，难以取舍；然后把那些没有什么价值的书扔掉——这种价值的评定是没有什么统一的惟一的标准的，可根据自己的需要视具体情况而定。一本书就像一根绳子，只有当它跟系着或捆着的东西发生关系时，它才有意义。同是一本书，对有的人毫无价值，对另外一个人说不定就有点用处。

　　读书的功夫要下在需要认真阅读、仔细品味的一类书上。这类书能满足你的精神需要，激发你的才智，帮助你完善自己。你要征服的也是这样的书。多好的书也不是供香客朝拜的祀奉物。

　　还有一些是供你消遣、娱乐的书，可在沉闷无聊的旅途上，在紧张疲劳之后，在工作之余，以及在睡不着觉的时候去读，而不必用正规的时间。我现在真感到时间宝贵，浪费不起，好象一天不再有24小时，只剩下20小时或18小时，其于的时间被电视和其他一些不用动脑子的活动占去了。我的窗台上和写字台周围书刊堆的过高了，就反省自己是不是读书的时间减少了，于是拼上几个晚上，把功课补齐。

　　当然，还有一部大书，每个人都需要终身不懈地精读粗读苦读喜读，它就是生活这部活书。读它不能代替读印刷的书；同样，读印刷的书也不能代替读它。（节选自蒋子龙《书的征服》）
